[0017] The present invention will be further described below in conjunction with the drawings.

[0018] Such as figure 1 As shown, the winding steel wire rope replacement method of the present invention includes the following steps:

[0019] Preparation: Lower the movable pulley group 4 of the wire rope winding system to the ground, place it in the wire rope replacement work area, and remove the limit switch on the drum 5;

[0020] Cutting: First, put down all the old steel wire ropes wound on drum 5 until only the end of the old steel wire rope pressed by the pressure plate is on the drum 5. Take a point on the outermost wire rope on the side of the first pressure plate 1 and cut it with a cutting torch For the old wire rope, loosen the first pressure plate 1 on the cut side reel 5, and remove the old wire rope between the wire rope cutting point D and the first pressure plate 1;

[0021] Connection: Use a cutting torch to fully weld the end of the old wire rope left on the movable ...

Abstract

The invention discloses a wound steel rope replacing method with simple operation, which comprises the steps of preparing, cutting an old steel rope, connecting ends of the old steel rope and a new steel rope, fixing two ends of the new steel rope, and the like. By adopting a mode that the old steel rope is divided into two parts, one of parts of the old steel rope is connected with the new steel rope, the new steel rope is led under the pull force of a winding drum to be wound on a movable pulley block and a fixed pulley block and then two ends of the new steel rope are fixed. The invention realizes the semi-automation of replacing the steel rope, simplifies the replacement operation, saves the replacement time, reduces the operating personnel, improves the safety, and is suitable for replacement operations of the steel ropes wound on various winding drums.

Description

technical field [0001] The invention relates to a method for replacing a steel wire rope, in particular to a method for replacing a steel wire rope wound on a reel of a hoisting machine. Background technique [0002] At present, the wire rope winding system used on the hoisting machinery includes a reel, a fixed pulley block, a movable pulley block and a wire rope threaded therebetween, and a limit switch is arranged on the reel. When it is necessary to replace the wire rope wound on the hoisting drum of the hoisting machinery, the following steps are generally required: [0003] Lower the movable pulley of the hook to the ground work area, cut off the steel wire ropes wound on the movable pulley block, loosen the screws at the pressure plate, and remove the wire ropes. [0004] Bind one end of the new steel wire rope with hemp rope and pull it to the hoisting drum by a human pull method and fix it on the pressure plate at one end of the drum, and then thread the other end ...
